I!) caught between the rolls may cause such release of the rolls that the rolls will cease to function cooperatively.

Another object is to provide simple and eflicient means for the purpose indicated.

-- These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 8 is a sectional view on line 8--8 of Fi The frame 10 may be of any suitable form and serves as a support for suitable bearings 11, 12, 13 and 14 for the cooperating rolls and 16. The bearings 11 and 12 are preferably fixed. and the bearings 13 and 14 are preferably slidable vertically of the frame. To this end, the frame has its sides 17 and 18 slotted for providing vertical ways 19 and 20 between the opposed branches 21 and 22 of side 17 and opposed branches 23 and 24 of side 18. Bearings 11 and 13 are disposed in way 19 and bearings 12 and 14 are disposed in way 20.

The roll 15 is supported by shaft 25 extending through bearings 11 and 12, and shaft 25 carries a suitable gear or cog 26 for meshing with a cog or gear 27 on shaft 28 that supports pins 'one of the catch Serial No. 567,509.

roll 16. Shaft 28 is supported by bearings 13 and 14. On shaft 25 is a suitable pul ley 29 or other means whereby power may be transmitted to shaft 25.

Cooperating cogs or gears such as 26 and 27 may be disposed at both ends of shafts 25 and 28. Suitable springs 30 are interposed between bearings 11 and 13 and between bearings 12 and 14.

A cross bar 31 has its opposite ends disposed in the upper ends of ways 19 and 20. Suitable springs 32 are disposed between bearing 13 and end 33 of bar 31 and between bearing 14 and end 34 of bar 31. Each end of the bar 31 is provided with a lug or detent 41. At each side of the frame is disposed a catch 35 that may engage with a detent 41 and retain the bar 31 in such position that springs 32 urge the roll 16 toward and against roll 15 for retaining the rolls and cogs in cooperative relationship. Upon release of the detents from the catches, the springs 32 and 30 and roll 16 are released. The power used for releasing the roll 16 is taken from shaft 25, see F i 4. On shaft 25 is a disk 36 carrying Any one of the pins 37 can actuate or trip the mechanism about to be described, for releasing roller 16.

At each side of the frame is provided a strap like member 38 and 39. The members 38 and 39 shown herein are not identical in shape, yet their functions are in major portion, the same. Each member 38 and 39 serves as a means for pivotally supporting members 35. Each catch member 35 is mounted on a pivot or suitable stud 40. V The catch members are moved about the axes of thepivots or studs 40 for release and engagement of the catches with their respective lugs or detents 41.

Springs 42 yieldingly urge the catches toward the sides of the frame so that the catches are normally and yieldingly retained in positions where they may contact and engage with the lugs or detents 41. The member 39 may be integral with the cap or housing 43 within which the cogs 26 and 27 are enclosed. The one member 35 is moved about its axis 40 for releasing end 34 of bar 31, by means of a rod 44, reciprocally supported by bearing blocks 13 and 14. A spring 45, having its opposite ends in abutment on bearing block 14 and collar 46, fixed on rod 44, yieldingly holds the rod in a position where the rod is inoperative on its cooperating catch member 35. A suitable abutment collar 47 may cooperate with bearing 13 to limit movement of rod 44 under the influence of spring 45. The end of rod 44, remote from its cooperating catch member 35 may be contacted by a cam 48 for imparting longitudinal movement to rod 44. The same cam is employed for actuating both catch members. The cam is, therefore, provided with two cam plates, viz., 49 and 50, each of which controls one catch member. The second catch member 35 carries a stud 51 that may be aligned with rod 44 and which I on operation by its cooperating cam plate 50 actuates the catch member about its axis 40. The cam plates 49 and 50 are-preferably arcuate so that movement of the cam plates in .opposite directions will have the same effect upon the rod 44 and stud 51 for releasing roll 16.

The cam body 48 is pivotally supported by a suitable stud or shaft 52 and shaft 52 may be supported by strap-like member 38, for example by means of cross-piece 53 carried by member 38. The body of cam 48 is U-shaped and a flat spring 54 is disposed between the arms thereof and the ends of the spring contact the lower edge of the strap member 38. The ends of the spring 54 may be angular and may project upwardly over the outer face of the strap member 38. The spring yieldingly holds the cam in a position in which the cam is inoperative for actuating the rod 44 and stud 51.

The cam body 48 carries a stud or shaft 55.

On shaft 55 is supported a trip finger 56 carrying a lug 57 that may be moved into the path of the pins 37. A spring 58 yieldingly holds the finger in such a normal position wherein the lug 57 is disposed out of the path of the pins 37.

The release of the wringer rolls to permit movement thereof out of cooperative relation is electro-magnetically effected. Thus, the trip finger may be actuated for introducing the lug 57 in the path of pins 37, by means of stem 59, carried by the armature 60 of electromagnet 61. (Normally the electromagnet is deenergized, and the spring 58 holds the armature at a distance from the core '62 of the electromagnet. The stem 59 may exi tend reciprocally through the core 62. The stem 59 may be manuallv actuated for tripping the device by manual depression of armature 60. End 63 of the electromagnet winding may be electrically connected with any suitable source of electrical energy, not

shown. If a motor is used to operate the wringer, the end 63 may be connected with the source of energy used for the motor, otherwise a battery may be connected to end 63.

End 64 of the winding is electrically connected to a switch 65 that may be mounted on the top member 66 of the frame 10. Other switches may be provided in parallelwith switch 65, and may be so positioned that an operators foot, knee or other part of the -might have both hands caught between the rolls, the operators head would be rather close to the top of the device and, therefore,

the operator could release her hands by merely blowing against a diaphragm 68, suspended by a lightly tensioned spring 69, and thereby effecting contactbetween contacts 70 and 71. Adjustment of the gap between contacts 70 and 71 may be effected in any suitable manner and with any means commonly used for such purpose. The casing 72 of the switch may be mounted on the top member in any suitable manner and may be so adjusted that the diaphragm may be actuated from any direction. If desired, a plurality of similar switches, fixed or adjustable relative to the frame, may be provided. Preferably the diaphragm in its normal position, closes the opening 73 in the truncated conical plate 74 of the device, and air gaps 75 are provided about the diaphragm, at the rear of plate 74,

whereby to obviate building up of pressure at the rear of the diaphragm that might hinder free and easy operation of the switch.

The cross bar 31 may be depressed by means of a suitable lever 76, pivoted in a suitable aperture 77 provided through the top, member 66. The lever serves to simultaneously, engage-both lugs 41 with their respective catch members, and the tripping of the finger 56 by any of the pins 37 serves to oscillate the cam 48 whereby to simultaneously release both lugs 41 from their respective catch members.
